FASTENING DEVICE FOR SHIIELDS.y

Application filed November 22, 1924. Serial No. 751,719.

(GRANTED UNDER THE ACT F MARCH Il, 1883; 22 STAT. L. 625.)

To alt whom t may concer/n.:

Be it known that I, HARRY HoisiNGToN, a citizen of the United States, and a resident of Davenport, county of Scott, and State of Iowa, have invented an Improvement'in Fastening Devices for Shields, of which the following is a specification.

The invention described herein may be used by the Government, or any of its officers or employees in prosecution of work for the Government, or by any othe-r person in the United States, without payment to me of any royalty thereon, in accordance with the act of March 3, 1883.

yThe subject of this invention is a fastening for shields.

On mobile gun carriages provided with shields it is desirable to fold the upper part of the shield when the carriage is swung to its limber for traveling.

The principal object of the present invention is to provide means for rigidly and securely holding the top carriage in either raised or lowered position and includes a forked brace hingedly connected to the top shield, its free end carrying a locking device engageable in a keeper or bracket on either side of the main shield.

To these and otherends, my invention consists ir the construction, arrangement, and combination of elements, described hereinaft-er and pointed out in the claims forming a part of this specification.

A practical embodiment of my invention is illustrated in the accompanying` drawings, wherein:

Fig. 1 is a front view showing the top shield in lowered or traveling position;

Fig. 2 is a rear view showing the top shield in the raised or firing position;

Fig. 3 is a view in side elevation of the shield as shown in Fig. 2;

Fig. t is a detail rear elevation of the brace; 4

Fig. 5 is a side view thereof;

Fig. G is a detail view of the plunger; and Fig. 7 is a detail view of the rear bracket. In carrying o-ut the invention, there is provided a. main shield 11 on which is hinged a top shield 12 which may be divided in certain types of guns. When the gun is in action it is obvious that the shield whose function is to protect the gunners and the delicate instruments on the gun, is in the raised position while when the gun carriage is in transit the top shield is in the lowered or folded position.

For the purpose of securely holding the top 'shield or shields in adjusted position there is provided a forked brace 13the forks pivoted on a rod 14 which is mounted in a pair of brackets 15 secured to the top shield 12. The free end of the brace is centrally bored to receive a plunger 16 and plunger spring 17. The plunger is adapted to be manually retracted in the bore by means of a pin 18 passing transversely therethrough and working in aligned blind slots 19 in the brace. The pin18 also serves to prevent loss of the plunger.

Mounted on both the front and rear sides of the main shield 11 are brackets or keepers respectively 2O and 21 preferably secured by rivets and formed with an aperture 22 for receiving the plunger 16.

In the views shown the rear keeper 21 is provided with a. transverse projection 23 engageable in a notched edge 24 on the brace when the brace is fastened in place. This provision is made to steady the top shield when in the raised position and to serve as an auxiliary catch or securing means in the event the plunger spring is rendered functionless. It will be readily apparent. that a spring catch may be substituted for the projection 23 and that if desired a similar construction might be prov'ided on the reverse side of the brace and on the front keeper.

While in the foregoing there has been illustrated and described such combination and arrangement of elements as consitute the preferred embodiment of my invention, it is nevertheless desired to emphasize the fact that interpretation of the invention should only be conclusive when made in the light of the subjoined claims.

I claim:

1. In combination with a main shield for guns, a top shield foldable thereon, brackets on one side of the top shield, a rod mounted in said bracket, a brace having forks pivoted to the rod, the free end of the brace formed with a central bore and blind slots in the sides of the brace and in communication with the bore, said portion of the brace further formed with a notched edge, a plunger and spring disposed in the bore, a pin passing through the plunger and slots, and keep- (lll ers formed with apertures to vreceive the plunger and mounted on both front an-drear of the main shield, the rear keeper formed with ar transverse projection engageable in the notched edge of the brace.

2. In combination With a main shield for guns, a top shield foldable thereon, brackets on one side of the top shield, a rodmounted in said brackets, a brace having forks pivoted to the rod, the tree end of the brace formed with a central bore, and blind slots in the sides of the brace and in communication with the bore, a plunger and spring disposed in the bore, a pin passingthrough the plunger and slots. and keepers formed with apertures to receive the plunger andv mounted on both front and rear of the main shield.

In combination with a main shield Jfor guns, a top shield toldable thereon, brackets on one side of the top shield, a` rod mounted in said brackets, a brace having forks pivoted on the rod, a plunger and spring therefor in the free end of the brace, means for manually retracting the plunger, keepers formed with apertures for receiving the plunger and mounted on the front and -rear of the main shield, and cooperating ineanson one of the keepers and the brace for auxiliarily retaining the brace in set position.

4. In combination with a main shield for guns, a top shield toldable thereon, brackets on one side of the top shield, a rod .mounted in said brackets, a brace having forks piroted on the rod, a plunger and spring theret'or in the free end of the brace, means for inanually retracting the plunger, keepers formed Withaperturcs for receivingthe plunger and mounted onvthe Jiront and rear of the main shield, a-nd an auxiliarily retaining means 'tor holding the brace in set position.

In combination with a main shield for suns, a top shield foldable thereon, a brace pivoted to the top shield, a plunger and plunger spring n iountedrin the free-'end ot said brace, means for manually reti-acting the plunger, keepers attached to both front and rear of the main shield and adapted to receive the plunger', and cooperating mez. ns on a keeper and the brace for auxiliarily retaining Ythe brace in set position.

6. In combination with a main shield tor guns, a top shield foldable thereon, a brace pivoted to the top shield, a plunger and plunger spring mounted in the free end of slid brace, means for manually retracting the plunger, and keepers attached `to both front and rear of the main shield and adapted t0 receive the plunger.
